[vox-tech] high-pitch noise when trying to raise the volume

[Hai Yi]

hello,

I have a problem with adjusting the volume when I watch the movie or
listen to the music: the sound becomes unbearable high-pitch noise
when I raise the volume (using alsamixer or other).

I hope I could be able to provide more details, however, there is not
too much info about it.

Anyone experience this kind of problem?

Thanks a lot,
Hai
